A cover, then, of "CREEP" by Radiohead. Interestingly, it works on a simple unchanging 4-chord progression throughout: verses, chorus and bridge ALL run on the same G-B-C-Cm chord sequence, although the melodic structure of all are VERY different.

This one was written very early one December morning, in a freezing cold train compartment, on my way home from College.
It was more than just the hard bunk and freezing temperatures inside that compartment that had kept me up this particular night.
